Local Tips for Mexico City
- ✓Base yourself in established neighborhoods like Roma Norte, Condesa, Polanco, Juárez, or Coyoacán, and treat the Centro Histórico as a daytime destination — after dark, keep to busy, well-lit streets and skip the areas locals consistently warn about, such as Tepito and Doctores
- ✓Never hail a taxi on the street — use Uber or DiDi (both work well here and record your route) or an authorized 'sitio' taxi from a marked stand, since unregulated street cabs have been linked to robberies and 'express kidnapping' incidents
- ✓Mexico City sits at roughly 2,240 meters (about 7,350 feet) of altitude — give yourself a day or two to acclimatize, drink extra water, go easy on alcohol at first, and don't be alarmed if stairs leave you short of breath
- ✓Don't drink the tap water — stick to bottled or purified water ('agua purificada'), which established restaurants also use for their ice, and ease into street food by picking busy stalls with high turnover
- ✓The Metro and Metrobús are cheap and extensive but extremely crowded at rush hour, when pickpocketing peaks — keep bags zipped in front of you, and women traveling alone can use the women-and-children-only cars at the front of Metro trains during peak times
- ✓The city's seismic alarm (alerta sísmica) sounds from public loudspeakers when a strong quake is detected, often giving precious seconds of warning — if you hear it, stay calm, move away from windows and building facades, follow locals toward open ground, and dial 911 for any emergency
